ClassStrategy.customLoad(JDBCStore store,
boolean subclasses,
JDBCFetchConfiguration fetch,
long startIdx,
long endIdx)
Implement this method to customize obtaining a result containing all
instances of this class.

StateComparisonVersionStrategy.customInsert(OpenJPAStateManager sm,
JDBCStore store)
This method is for class mappings that take over the insert
process, but still want to use this indicator for optimistic locking.

StateComparisonVersionStrategy.customUpdate(OpenJPAStateManager sm,
JDBCStore store,
Table table,
boolean record)
This method is for class mappings that take over the update
process, but still want to use this indicator for optimistic locking.
